Billionaire New York City Mayor Michael Bloomberg's pro-gun-control super PAC will finance $1.1 million in advertising for Virginia Democratic gubernatorial candidate Terry McAuliffe in the final weeks of the race, Politico reported Monday.

The ads will roll out Tuesday. The election is Nov. 5.

McAuliffe journeyed to New York in August to seek the mayor's support.

Bloomberg, a political independent, has spent more than $15 million on various gun control initiatives — and spent $1 million helping elect Newark Mayor Cory Booker to a U.S. Senate seat in New Jersey's special election to replace the late Frank Lautenberg, who championed gun control, The New York Post reported.

McAuliffe supports stricter gun laws, including an assault weapons ban, universal background checks, limiting the size of magazines and preventing people from buying more than one gun a month.

Roll Call reported Monday that the political action committee of the National Rifle Association has spent $466,000 on television and Internet ads highlighting McAuliffe-backed gun control measures.

The campaign of Republican Ken Cuccinelli, who supports a focus on mental health to reduce gun violence, slammed the ads as out-of-state interference.
